Airplay 2 speakers (Denon Home 250) set as stereo pair.

Is there an option to set up Airplay 2 compatible speakers as a stereo pair, just like the HomePod's? In the living room I have 2 "Denon Home 250" speakers that I would like to set as a stereo pair, using Airplay. When I follow the setup in the Home app, to set the HomePod's as a stereo pair in a room, the button "use as stereo pair" is not displayed.

Someone who can get me started?

All devices (MacBook Pro, iPhone XS, iPad Pro, Apple TV 4K and Denon Home speakers) have the latest update of their operating system.
